What is the rear fender of a car
The rear panel of the car trunk is located at the rear of the vehicle and is a body panel. It is connected to the frame by welding and mainly serves to protect the trunk and provide structural support
The rear panel of a car is an important part of the body structure, as can be understood from
Definition and Position
Youdaoplaceholder0 Basic definition
The rear panel is the rear baffle of the car trunk, located at the rear of the vehicle, between the external bumper and the interior of the trunk. It can only be fully visible when the rear bumper is removed.
It is composed of multiple steel plates welded together and is not a single integral structure.
The specific location covers the outer edge of the bottom of the trunk and is connected to components such as the bottom plate of the suitcase and the water channel.
Youdaoplaceholder0 Structural features
It includes the main body and the edge banding (welded edge, used for installing the sealing strip).
It belongs to the body panel and is fixed to the frame by welding.
Function and Role
Youdaoplaceholder0 Core function
Youdaoplaceholder0 Protective function : To prevent mud, water and other debris from entering the trunk.
Youdaoplaceholder0 Structural support : Maintains the overall shape of the rear of the vehicle, but deformation has little effect on handling performance.
Youdaoplaceholder0 Safety performance
In rear-end collisions, it is the first to be affected and needs to absorb part of the impact force to reduce the risk of occupant injury.
Maintenance and second-hand car evaluation
Youdaoplaceholder0 Repair principle
Youdaoplaceholder0 Priority sheet metal repair : Minor deformation can be repaired by drawing or hamming and is not considered an accident vehicle.
Youdaoplaceholder0 Consequences of cutting repair : If cutting replacement is necessary, the vehicle will be classified as an accident vehicle, resulting in reduced strength and depreciation of used cars. After the repair, anti-rust treatment should be carried out on the weld points (the welded parts are prone to rust).
Youdaoplaceholder0 Used car inspection points
The trunk needs to be emptied to check for any deformation or repair marks on the rear panel.
Use maintenance records and insurance records to assist in determining whether a major accident has occurred.
Association with other components
It is an adjacent but independent component to the rear bumper, and the rear fender is located on the inner side of the bumper.
If the rear fender and the floor of the spare tire deform simultaneously, it may still not affect the vehicle's performance.
The main function of the rear panel of a car
Youdaoplaceholder0 Protect occupant safety and absorb impact force
The rear panel is located between the trunk and the exterior of the vehicle. It is the first component to be affected in rear-end collisions. By deforming, it absorbs impact energy and reduces harm to the occupants inside the vehicle.
Its materials are mostly stainless steel or high-strength metals, formed through stamping processes, and it has both toughness and rigidity.
Youdaoplaceholder0 Isolation and protection function
As a "partition" for the trunk, it prevents external mud, water and debris from entering the vehicle, while protecting the items in the trunk from being squeezed.
It works in coordination with the rear bumper to form a double-layer protective structure.
Youdaoplaceholder0 Structural support and body integrity
Although it is a body panel, it is connected to the frame by welding and plays a certain auxiliary role in maintaining the overall shape of the vehicle.
Minor deformation has a minimal impact on handling performance, but when severe damage requires cutting and replacement, it may reduce the vehicle's strength and affect the value of the used car.
Youdaoplaceholder0 Summary : The core function of the rear panel is safety protection and structural isolation. Its design takes into account the functional requirements of energy absorption in case of an accident and daily use. When maintaining or purchasing a car, special attention should be paid to its integrity to avoid vehicle depreciation due to cutting and repair.
